# LAR — Rights and licensing

**Canonical Manifest:** https://lar.md/.well-known/lar.json
**As of:** 2026-07-27

This surface publishes artifacts under different licenses. The manifest can point at one
rights document; it cannot yet say which license governs which leaf. Until it can, this page
is that statement, and `policies.terms` in the manifest resolves here.

## Per artifact

| Artifact | License | Where it lives |
|---|---|---|
| Working paper, *Layered Agentic Retrieval* | **CC BY-SA 4.0** | `/lar/working-paper.md`, and the archival deposit at [10.5281/zenodo.21622424](https://doi.org/10.5281/zenodo.21622424) |
| Specification, JSON Schema, worked examples, code | **Apache-2.0** | [github.com/lar-spec/lar](https://github.com/lar-spec/lar) — see its [LICENSE](https://github.com/lar-spec/lar/blob/main/LICENSE) |
| This site's own prose (`/`, `/lar/about.md`, `/llms.txt`, this page) | **CC BY-SA 4.0** | lar.md |
| The manifest and its structure as a pattern | Unlicensed by intent — the pattern is offered to the commons | — |

For the paper, cite the DOI rather than this copy.

**A note on the paper's two lives.** The working paper develops material that also appears, in
different form, in an appendix to the forthcoming book *Selling to Agents* by the same author.
The standalone paper published here is CC BY-SA 4.0; the book version is under standard
commercial copyright. The two are not identical.

## Why this is a page and not a field

The copy of the paper served at `/lar/working-paper.md` is byte-identical to the archival
deposit, and that identity is what makes the claim "text identical to the SSRN version"
checkable by anyone. So the license cannot be written into the file: doing so would break the
verification it is meant to support. It has to be declared *about* the leaf, from outside it.

LAR v0.1 has nowhere to put that. `context` maps a name to a URI string, so a leaf can be
pointed at but not described — no license, no digest, no last-modified. A surface that serves
artifacts under more than one license therefore has exactly one machine-reachable rights
statement for all of them, which is wrong the moment the licenses differ. This page is the
honest workaround. Per-leaf metadata is an open question for v0.2 — see the
[repository issues](https://github.com/lar-spec/lar/issues).
